On rpm-ostree distributions like Fedora SilverBlue /home (and various other well known locations) are symlinks to somewhere beneath /var. The path_is_encrypted() method uses O_NOFOLLOW and as a result will return ELOOP on /home. This causes test-blockdev-util to abort. Add ELOOP to the ignorable set of errnos for testing.
